Installation Best Practice - Raid 1 or Raid 10

Question

I am getting ready to install SQL 2005 on a Server 2008 box. The box has a Raid 1 where the OS sits and a Raid 10 for the data. When installing SQL (program files), where should I put it? On the raid 1 or 10? Can I do the install on the Raid 1 and put the actual DBs on the raid 10? Sorry for the noob type of question. The only thing I came up with in a search is people debating which type of raid is best. Either way, I need the actual data on the raid 10 as that is my larger store.
